>As mentioned above, you simply cannot compare a smartphone operating system where one handles, emails (in the cloud anyway) some personal apps and a browser to a full desktop operating system where among many other things serious work is done as well as private and enterprise data is stored.

You definitely can, Feel free to disagree, but many would argue the comparison is fair, especially considering a smart phone has replaced a desktop or a laptop for many people. But to say in such absolute terms the comparison is not appropriate is naive.
